In-depth filtration is performed using porous filtration media (e.g, porous cartridges) with a thickness much higher than the desired particle size in the paint. Undesired particles are held in the pores of the filter and, thus the paint is filtered.
Filtration of coatings with “deep filtration method” under an applied pressure using cartridge filters having controlled porous structures. Presently, cartridge filters of 1µm to 100µm pore sizes are used for paint filtration processes.
A process in which unwanted particles presented in paint are retained on a certain mesh size sieve.
